problem with regex.c

[Olle Eriksson]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.1.1 (alpha-dec-osf5.1, OSF/Motif Version 1.2.4)
 of 2001-10-29 on skalman.cb.uu.se
configured using `configure  --with-x-toolkit=motif'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When building Emacs 21.1 on a Tru64 V5.1 Compaq system, using the
native C-compiler, compilation of src/regex.c fails because of
multiple contradictory deklarations of regcomp, regexec etc. The 
problems seems to be that the 

#ifndef emacs

that is suppose to hide the second definition doesn't do that, probably
because the symbol emacs is not defined.
